Which of the following is NOT one of the five basic fundamentals that commanders and leaders must use?

The correct choice indicates that "Strategy" is not one of the five basic fundamentals that commanders and leaders must utilize. In the context of Army Training and Leader Development, the five basic fundamentals, often referred to as the foundational elements for operational success, typically include movement, communication, and sustainment activities.

Movement is about positioning units effectively on the battlefield, ensuring they are in the right place at the right time. Communication ensures that commands and information flow efficiently among all levels of the chain of command, which is crucial for coordinated actions. Sustainment refers to the logistical support necessary to maintain operations, including supply and maintenance.

While strategy is an important component of military planning and execution, it falls under broader operational concepts and decision-making processes rather than being classified as one of the basic fundamentals in training and development frameworks. Understanding these distinctions helps ensure leaders can effectively develop their units while adhering to recognized principles.
